used extensively in North America, including at the 1948 US Olympic trials. The Bulova device was activated by the sound of the starting gun firing, rather than by a direct connection, which means that the times were around 0.02 seconds faster than reality. The 1948 Olympics, however, continued to use Omega timing with a device called the 'Magic Eye', developed by British Race Finish Recording Co. Ltd. The automatic times produced in the 1948 Olympics have never been released, but examination of the photos at the finish means that margins have been calculated to 1/100 second accuracy. In 1952 the Omega Time Recorder was the first to use a quartz clock and print out results, earning the company a prestigious Cross of Merit from the Olympic Committee. Clocks were added to slit cameras for automatic time-stamping, accurate to the 100th of a second. Despite these improvements, the overall system was similar to that used in London in 1948 (the Racend Omega Timer). The average difference between the FAT and manual times for the men's 100 meters was 0.24 seconds, although this ranged from 0.05 seconds to 0.45 seconds; for example, the average difference for the six runners in the men's 100 meter final was 0.41 seconds; while the average difference in the women's 100 meters was also 0.24, but only 0.22 in the final. In the men's 200 meters, the average difference was 0.21 seconds, and in the men's 400 meters the average difference was 0.16 seconds. In 1956 the average difference between the FAT and manual times for the men's 100 meters was 0.19 seconds, ranging from -0.05 to 0.34 seconds. In the men's 200 meters, the average difference was 0.16 seconds, and in the men's 400 meters the average difference was 0.11 seconds. In 1960 the average difference between the FAT and manual times for the men's 100 meters was 0.15 seconds, ranging from -0.05 to 0.26 seconds. In the men's 200 meters, the average difference was 0.13 seconds, and in the men's 400 meters the average difference was 0.14 seconds. In 1964, although manual timing was also used at the Olympics, the official times were measured with a FAT system but were given the appearance of hand times. For example, Bob Hayes won the 100 meters in a FAT time of 10.06 seconds, which was converted to an official time of 10.0 seconds: the FAT systems in
